Excellent website! Looking through the Francis Crawshay’s photograph album (Arthur Lewis Collection), page 3, ninth photo down on left side of page: looks very much like Aberaman House (later site of NCB offices, Farm Road, Aberaman – no longer in existence). There is a series of photographs available on the Digital Archive of the Rhondda Cynon Taf Service (enter Aberaman House in the search box)
I have just discovered this website and recognise a number of photographs on the Francis Crawshay site. In particular I believe the house on the third page, six down on the left hand column is Rose Cottage in Cathedine, former home or Rose Crawshay (1828-1907). This house has since been renamed as Tower House in Cathedine. I also believe that a number of the other unknown pictures are in and around Cathedine and the B4560.
Do you happen to have any more photographs from this collection please. They are fascinating!!!
